MACHINE FOR DRIVING GUIDE RODS IN WINGS F WINDOW-SCREENS.

SPECIFICATION forming part of Letters Patent No. 427,584, dated May 13,1890. Application fi ed September '7, 1839. $erial1l0. 323,260. (Nomodel.)

To all whom it may concern.-

Be it known that I, FRANK LEDUC, of the city of Detroit, in the countyof Wayne and State of Michigan, have invented new and usefulImprovements in Machines for Driving Guide-Rodsin WVings ofWindow-Screens; and I hereby declare that the following is a full,clear, and exact description thereof, ref erence being had to theaccompanying drawings, which form a part of this specification.

My invention relates to an improvement in machines for fasteningguide-rods in wings of window-screens.

The objects of my improvement are, first, to securely clamp and hold theends of the wings while the guide-rod is being driven into the slot inthe wing and the arm or prong of the rod driven into the wood; second,to prevent the splitting of the wood by the arm or prong as it is drivenin; third, to drive the guide-rod into the slot in the wing and the armor prong into the Wood, and to retract the driving-plate and release thewing from the clamp; and it consists in the means for clamping the endsof the wings and in the mechanism actuating the clamps in the means forholding them While clamping the wings, and in the means to return themto their normal position, and in the means for driving the guide-rodinto the slot in the wing and the arm or prong of the guide-rod into thewood, and the mechanism for operating the driving-plate and to retractit from the slot of the wing, and in the peculiar combination,arrangement, and construction of the various parts, as hereinafter moreparticularly set forth.

As a guiderod is necessary at each end of the wing of a window-screen, lhave constructed my machine in two sections or double, so as to drivethe two at one operation. It is evident the one section or a singlemachine would do the work as Well as the double one, but only one halfas fast. Therefore, when speaking of any part of the machine itsduplicate is included, when there is such duplicate, in the othersection.

Figure 1 is a front elevation of my machine, one section only beingshown. Fig. 2 is a is a vertical section through the table andguide-plate, on the line at a: in Fig. 5. Fig. 4 is a perspective viewof the stop for holding down the clamps detached from the table. Fig. 5is a plan view of the table and guide-plate, one section only beingshown. Fig. 6 is a horizontal section through the top of the bar G inFig. 1. Fig. 7 is a perspective view of a part of the wing, showing theslot and the guiderod driven in and fastened.

In the drawings, A represents the table of my machine supported on thestandards A A. This table extends the whole length of the two sectionsof my device. The standards are in sets of four, one set under eachsection. Each set is connected by proper girts below the table. A doublegirt A is placed a short distance below the table and a little to therear of the center, extending lengthwise of the table, and is supportedby proper crossgirts inserted in the'standards A A". This double girtforms a slot, in which a bellcrank lever is pivoted, and a linkconnected to one arm of the lever reciprocates.

B is a movable guide-plate held in position on the table by theset-screws and nuts I) b, which pass through the slots cm in the table.This guide-plate is so set that its upper face is level with the loweredge of the slot in the wing for the reception of the guide-rod, so thatwhen the guide-rod is forced forward off of the guide-plate by theforward movement of the drivingplate it enters without any difficulty orobstruction the slot in the wing.

O C C are ways on the guide-plate, in which the driving-platereciprocates.

D is a thin plate sliding in the ways C, C, and OZwhich, by its forwardmovement, drives the guide rod into the slot in the wing and the prongor arm of the rod into the Wood.

(Z isan arm or extension of the plate D, extending across theguide-plate and into the ways 0 on the side of the plate. This armserves to move and keep the free or outer end of the guide-rod in theproper position while the arm or prong on the inner end is being driveninto the wood.

B is a bar or plate extending across the inner end of the guideplate andabove the driving-platc which slides under it. This plate holds theguide-rod in position for entering the slot in the wing.

' ards of the table.

The long arm of the bell-crank lever E projects upward through the slotto in the table and guide-plate, and is limited in its movement by theends of this slot. This arm also passes through the aperture (l' in thedrivingplate D. As this aperture is just large enough to permit of thefree passage of the arm of the lever, the forward and backward movementof the lever carries with it the drivingplate D. The lever E is pivotedin the slot in the double girt A at e. A link F is pivoted to the shortarm of the lever E and at its lower extremity to the barG. The bar Gextends beneath the two sections of my machine, and in each has the linkF pivoted to it, and is twisted or flattened at the center to give abearing to the lever II, by which it is actuated. The bar G isstrengthened by the truss-bar G, which is under it and bolted to it atits ends with a truss in the center.

P P arecoiled springs attached at one end to the bar G and at the otherend to the double girt A one being under each section.

The lever H is pivoted at its inner end to the standard H, which isfirmly secured by proper bolts to the floor in rear of the stand- Thelever H rests on the center of the bar G, and extends out beyond thetable and forms a foot-treadle. The downward movement of this leverforces down the bar G, which draws down the link F and the short arm ofthe bell-crank lever E. This brings forward the arm of the lever, whichprojects upward through the slot a in the table and the guide-plate andforces forward the driving-plate D, which drives the guiderod into theslot and the arm or prong into the wood of the wing. When the weight istaken oif of the lever H, the contraction of the coiled springs P Preverses the whole movement and brings all the parts back to theirnormal position.

I is a broad fiat clamp having an arm I at right angles with the plateextending down through a slot in the rear edge of the table. The arm Iis slotted at its lower end for the reception of the bar K, whichconnects and operates the clamp on the two sections. The arm I issecured on the bar K by the setscrews it, which allows the position ofthe clamp on the bar to be changed to suit the length of wing to beoperated upon. A pitman L connects the lower arm I of the clamp to thebowed lever O, which is pivoted at its 55,

inner end to the standard 0, which is firmly attached to the floorin-the rear and at one side of the standard H. The lever O is bowedupward to pass over and allow free play to the bar G below it. As thereare two clamps, there are two pitmen and two levers; but the levers areconnected by bolts as the clamps are by the bar K, and both are moved atthe same time.

P is a coiled spring attached at its lower end to the bolt 13 betweenthe two levers O O, and at its upper end to the under side of the table.

R is a stop pivoted to the under side of the table near the bar K andhas a handle 0", by which it is moved, projecting above the table. Thenthe clamps are drawn down, this stop is swung around between the underside of the table and the bar K and holds the clamps down while theguide-rod is being driven into the wing. \Vhen the operation iscomplete,

the stop is removed bythe operator, and the clamps are forced upward bythe action of the spring P.

In operating my machine the wing is placed on the table with its endsunder the clamps, the slot in the wing being turned toward the front oropen toward the operator. The operator, having placed the guide-rods tobe driven into the wing in proper position, steps on the two levers O 0,attached to the clamps. His weight brings the clamps down 011 the wings.The stop is then swung around between the table and the bar connectingthe two clamps. The operator then changes his weight to the leveractuating the bell-crank lever, and, bringing that down, pushes thedriving-plate forward by its long arm proj ecting above the table. Thedriving-plate forces the guide-rod into the slot and the arm or prong ofthe guide-rod into the wood of the wing, the clamp preventing thesplitting of the wing by the arm or prong of the rod as it is driven in.The operator changes his weight to the clamp-levers and the springs P Pcause the bar G to rise, and that throws up the bell-crank levers, andthey retract the driving-plate from the wing. The operators remove thestop and the spring P forces the clamp up, and the wing is released andre moved and another placed in position, and the operation is repeated.

It will be readily seen that it would be almost impossible to drive thisguide-rod into the slot and into the wood by hand, andthat tools wouldeven then have to be constructed for that especial purpose, and the workwould IIO be slow and unprofitable, while with my ma chine it can bedone about as fast as the wings and rods can be placed in position andre moved.
